The threadedDevice node is an abstract node that other nodes inherit from. In this node, there is a separate thread that is started when the node is created. This thread is used for acquiring data from a device. This secondary thread will push data into the node using mutex locking. When the data has been acquired, the thread will mark the output attribute as dirty so that compute in the main thread will be called. The compute method will acquire the data and set the attribute accordingly. This allows the threaded node to drive a plug such as translate continuously without being in playback mode.
